城市区域水污染生态修复的实验分析研究
|
摘要
针对传统活性污泥法在恢复城市区域水污染生态工艺中存在的去除效果不佳的问题,对基于膜生物反应器的污水处理工艺进行实验研究。所采样的实验装置使用了两个平板型超滤膜组成超滤池,并采用了硝酸盐循环和污泥循环工艺,针对微污染物采用臭氧化和粒状活性炭过滤两种工艺进行处理。经过17个实验周期的反复实验,对所得出的实验数据进行分析发现,实验装置能够较好去除城市污水中常见的富营养物质、微污染物,并相对于传统污水处理工艺能较好控制温室气体排放,能够满足各种对城市区域污水高效生态恢复的需求。
In view of the problem of poor removal of traditional activated sludge process in the restoration of urban water pollution ecological process,the experimental research on wastewater treatment process based on membrane bioreactor was carried out.The sampled experimental device uses two flat-type ultrafiltration membranes to form an ultrafiltration tank,and adopts a nitrate cycle and a sludge circulation process,and processes the micro-pollutants by ozonation and granular activated carbon filtration.After repeated experiments in 17 experimental cycles,the experimental data were analyzed and found that the experimental device can better remove the common nutrient and micro-pollutants in urban sewage,and can better control the greenhouse compared with the traditional sewage treatment process. Gas emissions can meet a variety of needs for efficient ecological restoration of wastewater in urban areas.
